CSIDE Dye Release Experiments. In The Cross-Surfzone/Inner-shelf Dye Exchange (CSIDE) Study

The Cross--Surf-zone/Inner-shelf Dye Exchange (CSIDE) experiment was conducted in the fall of 2015 in Imperial Beach CA to study the exchange of tracers, like pollutants, between the surfzone (where waves break) and the inner-shelf (shallow shelf just offshore of the surfzone). A bright pink dye tracer was released into the surf-zone and Tijuana River Estuary to quantify the exchange and to measure the amount of along-shore and cross-shore dispersion. This research is applicable to understanding transport of a variety of tracers including contaminants, larvae, and more in the nearshore region where humans and ecosystems are directly impacted.
